Vivianite with cleavelandite

Item Description

Vivianite is a rare species from Brazil, and large vivianite crystals of this quality have been found, to my knowledge, only recently at this mine (in the last 2-3 years). This is a choice miniature from the finds, with sharp, translucent crystals and, unusually, some cleavelandite matrix. This proves that this is a pegmatitic vivianite, which is extremely uncommon worldwide. Normally this species forms in phosphate pods, or in phosphate quarries often related to fossilized material there., but seldom in gem pegmatite environments. Complete all around, this is a very elegant specimen from a find in which most pieces could only charitably be described as "clunky" to the eye.
